Beginner Using BS4 - Cannot Obtain Divs on Page - python

Below is my code. I'm trying to obtain all the divs within that class. There are 15 I believe, however, the code returns 0. How do I parse the page in order to return the divs, and I would also like to obtain the links with them.
Thank you.

"User-agent": "Your_Header"

Python / BeautifulSoup webscraper returning "None"

trying to build a webscraper to return lists of freelance gig postings on different websites into one place. My code is below and it keeps returning "None". I'm a bit stuck at this point, if you can help identify why it keeps doing this that would be great.

I have no idea what exactly you are trying to extract from the scraped web page requests. Here's what I tried from my end:
Your links variable are null or empty lists since there is no such querySelector present for the web page you're trying to scrape. For example, the console of the first web page that you are scraping (the element you're trying to scrape doesn't exist):
I would recommend you to confirm the element you're trying to scrape and confirm it's class.
Another Point of Consideration:
When you will print your soup variables you will notice that you get CloudFare as the output.

Cannot find the table data within the soup, but I know its there

I am trying create a function that scrapes college baseball team roster pages for a project. And I have created a function that crawls the roster page, gets a list of the links I want to scrape. But when I try to scrape the individual links for each player, it works but cannot find the data that is on their page.
This is the link to the page I am crawling from at the start:
https://gvsulakers.com/sports/baseball/roster
These are just functions that I call within the function that I am having a problem with:
def parse_row(rows):
return [str(x.string)for x in rows.find_all('td')]
def scrape(url):
page = requests.get(url, headers = headers)
html = page.text
soop = BeautifulSoup(html, 'lxml')
return(soop)
def find_data(url):
page = requests.get(url, headers = headers)
html = page.text
soop = BeautifulSoup(html, 'lxml')
row = soop.find_all('tr')
lopr = [parse_row(rows) for rows in row]
return(lopr)
Here is what I am having an issue with. when I assign type1_roster with a variable and print it, i only get an empty list. Ideally it should contain data about a player or players from a players roster page.
# Roster page crawler
def type1_roster(team_id):
url = "https://" + team_id + ".com/sports/baseball/roster"
soop = scrape(url)
href_tags = soop.find_all(href = True)
hrefs = [tag.get('href') for tag in href_tags]
# get all player links
player_hrefs = []
for href in hrefs:
if 'sports/baseball/roster' in href:
if 'sports/baseball/roster/coaches' not in href:
if 'https:' not in href:
player_hrefs.append(href)
# get rid of duplicates
player_links = list(set(player_hrefs))
# scrape the roster links
for link in player_links:
player_ = url + link[24:]
return(find_data(player_))
A number of things:
I would pass the headers as a global
You are slicing 1 character too late the link I think for player_
You need to re-work the logic of find_data(), as data is present in a mixture of element types and not in table/tr/td elements e.g. found in spans. The html attributes are nice and descriptive and will support targeting content easily
You can target the player links from the landing page more tightly with the css selector list shown below. This removes the need for multiple loops as well as the use of list(set())
import requests
from bs4 import BeautifulSoup
HEADERS = {'User-Agent': 'Mozilla/5.0'}
def scrape(url):
page = requests.get(url, headers=HEADERS)
html = page.text
soop = BeautifulSoup(html, 'lxml')
return(soop)
def find_data(url):
page = requests.get(url, headers=HEADERS)
#print(page)
html = page.text
soop = BeautifulSoup(html, 'lxml')
# re-think logic here to return desired data e.g.
# soop.select_one('.sidearm-roster-player-jersey-number').text
first_name = soop.select_one('.sidearm-roster-player-first-name').text
# soop.select_one('.sidearm-roster-player-last-name').text
# need targeted string cleaning possibly
bio = soop.select_one('#sidearm-roster-player-bio').get_text('')
return (first_name, bio)
def type1_roster(team_id):
url = "https://" + team_id + ".com/sports/baseball/roster"
soop = scrape(url)
player_links = [i['href'] for i in soop.select(
'.sidearm-roster-players-container .sidearm-roster-player h3 > a')]
# scrape the roster links
for link in player_links:
player_ = url + link[23:]
# print(player_)
return(find_data(player_))
print(type1_roster('gvsulakers'))

BeautifulSoup generating inconsistent results

I'm using BeautifulSoup to pull data out of Reddit sidebars on a selection of subreddits, but my results are changing pretty much every time I run my script.
Specifically, the results in sidebar_urls changes from iteration to iteration; sometimes it will result in [XYZ.com/abc, XYZ.com/def], other times it will return just [XYZ.com/def], and finally, it will sometimes return [].
Any ideas why this might be happening using the code below?
sidebar_urls = []
for i in range(0, len(reddit_urls)):
req = urllib.request.Request(reddit_urls[i], headers=headers)
resp = urllib.request.urlopen(req)
soup = BeautifulSoup(resp, 'html.parser')
links = soup.find_all(href=True)
for link in links:
if "XYZ.com" in str(link['href']):
sidebar_urls.append(link['href'])
It seems you sometimes get a page that does not have a side bar. It could be because Reddit is recognizing you as a robot and returning a default page instead of the one you expect. Consider identifying yourself when requesting the pages, using the User-Agent field:
reddit_urls = [
"https://www.reddit.com/r/leagueoflegends/",
"https://www.reddit.com/r/pokemon/"
]
# Update this to identify yourself
user_agent = "me#example.com"
sidebar_urls = []
for reddit_url in reddit_urls:
response = requests.get(reddit_url, headers={"User-Agent": user_agent})
soup = BeautifulSoup(response.text, "html.parser")
# Find the sidebar tag
side_tag = soup.find("div", {"class": "side"})
if side_tag is None:
print("Could not find a sidebar in page: {}".format(reddit_url))
continue
# Find all links in the sidebar tag
link_tags = side_tag.find_all("a")
for link in link_tags:
link_text = str(link["href"])
sidebar_urls.append(link_text)
print(sidebar_urls)

Scraping and parsing multi-page (aspx) table

I'm trying to scrape information on greyhound races. For example, I want to scrape http://www.gbgb.org.uk/RaceCard.aspx?dogName=Hardwick%20Serena. This page shows all results for the dog Hardwick Serena, but it is split over several pages.
Inspecting the page, it shows under the 'next page' button:
<input type="submit" name="ctl00$ctl00$mainContent$cmscontent$DogRaceCard$lvDogRaceCard$ctl00$ctl03$ctl01$ctl12" value=" " title="Next Page" class="rgPageNext">.
I was hoping for a HTML link, that I could use for the next iteration of the scrape, but no luck.
Further inspection, by looking at network traffic, shows that the browser send a horribly long (hashed?) string for __VIEWSTATE, among others. Likely to protect the database?
I'm looking for a way to scrape all pages of one dog, either by iterating over all pages, or by increasing the page length to show 100+ lines on page 1. The underlying database is .aspx.
I'm using Python 3.5 and BeautifulSoup.
current code:
import requests
from bs4 import BeautifulSoup
url = 'http://www.gbgb.org.uk/RaceCard.aspx?dogName=Hardwick%20Serena'
with requests.session() as s:
s.headers['user-agent'] = 'Mozilla/5.0'
r = s.get(url)
soup = BeautifulSoup(r.content, 'html5lib')
target = 'ctl00$ctl00$mainContent$cmscontent$DogRaceCard$btnFilter_input'
data = { tag['name']: tag['value']
for tag in soup.select('input[name^=ctl00]') if tag.get('value')
}
state = { tag['name']: tag['value']
for tag in soup.select('input[name^=__]')
}
data.update(state)
numberpages = int(str(soup.find('div', 'rgWrap rgInfoPart')).split(' ')[-2].split('>')[1].split('<')[0])
# for page in range(last_page + 1):
for page in range(numberpages):
data['__EVENTTARGET'] = target.format(page)
#data['__VIEWSTATE'] = target.format(page)
print(10)
r = s.post(url, data=data)
soup = BeautifulSoup(r.content, 'html5lib')
tables = soup.findChildren('table')
my_table = tables[9]
rows = my_table.findChildren(['th', 'tr'])
tabel = [[]]
for i in range(len(rows)):
cells = rows[i].findChildren('td')
tabel.append([])
for j in range(len(cells)):
value = cells[j].string
tabel[i].append(value)
table = []
for i in range(len(tabel)):
if len(tabel[i]) == 16:
del tabel[i][-2:]
table.append(tabel[i])
In this case, for each page requested a POST request is issued with form url encoded parameter __EVENTTARGET & __VIEWSTATE :
__VIEWSTATE can be easily extracted from an input tag
__EVENTTARGET is different for each page and the value is passed from a javacript function for each page link so you can extract it with a regex :
<a href="javascript:__doPostBack('ctl00$ctl00$mainContent$cmscontent$DogRaceCard$lvDogRaceCard$ctl00$ctl03$ctl01$ctl07','')">
<span>2</span>
</a>
The python script :
from bs4 import BeautifulSoup
import requests
import re
# extract data from page
def extract_data(soup):
tables = soup.find_all("div", {"class":"race-card"})[0].find_all("tbody")
item_list = [
(
t[0].text.strip(), #date
t[1].text.strip(), #dist
t[2].text.strip(), #TP
t[3].text.strip(), #StmHCP
t[4].text.strip(), #Fin
t[5].text.strip(), #By
t[6].text.strip(), #WinnerOr2nd
t[7].text.strip(), #Venue
t[8].text.strip(), #Remarks
t[9].text.strip(), #WinTime
t[10].text.strip(), #Going
t[11].text.strip(), #SP
t[12].text.strip(), #Class
t[13].text.strip() #CalcTm
)
for t in (t.find_all('td') for t in tables[1].find_all('tr'))
if t
]
print(item_list)
session = requests.Session()
url = 'http://www.gbgb.org.uk/RaceCard.aspx?dogName=Hardwick%20Serena'
response = session.get(url)
soup = BeautifulSoup(response.content, "html.parser")
# get view state value
view_state = soup.find_all("input", {"id":"__VIEWSTATE"})[0]["value"]
# get all event target values
event_target = soup.find_all("div", {"class":"rgNumPart"})[0]
event_target_list = [
re.search('__doPostBack\(\'(.*)\',', t["href"]).group(1)
for t in event_target.find_all('a')
]
# extract data for the 1st page
extract_data(soup)
# extract data for each page except the first
for link in event_target_list[1:]:
print("get page {0}".format(link))
post_data = {
'__EVENTTARGET': link,
'__VIEWSTATE': view_state
}
response = session.post(url, data=post_data)
soup = BeautifulSoup(response.content, "html.parser")
extract_data(soup)

Python Pagination Loop

I'm doing some simple web scraping, and need to find a better way to loop through pagination on the target site. The only way I could do this was to write 10 + "for loops" to get it to work.
Basically I'm looking for a "Next" icon in the url, if it exist, I need to grab the parent link of the icon image and append it to the url, go to the new updated url, and search for the same icon and repeat until I get to the last page (the icon will be gone).
How could I perform this without hard coding a bunch of for loops?
url = "http://www.somewebsite.com/"
r = requests.get(wurl)
soup = BeautifulSoup(r.text, "lxml")
for img in soup.findAll("img"):
if "/Next_Icon" in img["src"]:
link = img.find_parent("a", href=True)
extLink = (link["href"])
url = "http://www.somewebsite.com/" + extLink
url_stack = ["http://www.somewebsite.com/"]
while url_stack:
wurl = url_stack.pop()
r = requests.get(wurl)
soup = BeautifulSoup(r.text, "lxml")
for img in soup.findAll("img"):
if "/Next_Icon" in img["src"]:
link = img.find_parent("a", href=True)
extLink = (link["href"])
url = "http://www.somewebsite.com/" + extLink
url_stack.append(url)
You should use list to store all the urls
